Abstract

In this study, adsorption tests were performed for three different dyes: methylene blue, Basic Blue 41, and Acid Red 266. Activated carbon prepared from sugarcane bagasse was used as the adsorbent material. The following activators were used: sulfuric acid, orthophosphoric acid, and zinc chloride, with the latter in two different ratios. Pyrolysis was performed on the chemically activated material, and material without prior activation was also prepared for comparison. The activated carbon was used in batch tests with stirring with the three dyes mentioned above. In general, greater adsorption is achieved with all activated carbons against methylene blue, except for the activated carbon made from sugarcane bagasse activated with zinc chloride in a 1-1 ratio, which adsorbs Basic Blue 41 in large quantities; with this activated carbon
the best results are obtained in both kinetic and adsorption tests.
